Cisco 26xx/36xx/72xx Router Simulator (Windows)
admin | May 29, 2007UPDATE: I highly recommend anyone interested in Dynamips to check-out GNS3 (Graphical Network Simulator). It’s designed around Dynamips, Dynagen, and Pemu. Cisco IOS/PIX binary images not included!

Dynamips is a Cisco router emulator. It support various Cisco 2600, 3600, 3700, and 7200 series router models.
Dyangen is a front-end for Dynamips router emulator. It utilizes Dynamips’ Hypervisor mode to make lab simulation management very easy.
Installing / Running Dynamips and Dynagen on Windows (XP, 2003, Vista):
- Install WinPcap 4 (Windows Packet Capture Library) from WinPcap.org (link to auto-installer).
- Install the latest version of the Dynamips/Dynagen “package” installer from SourceForge.
NOTE: April 29th, 2007 build is labeled: dynagen-0.9.2_dynamips-0.2.7-RC3_Win_XP_setup.exe
NOTE: Users with Vista UAC enabled may encounter issue(s) when trying to run Dynamips/Dynagen. Solutions:
- Disable UAC!
- Run the Dynamips server and Dynagen as Administrator; however, you must first modify the “dynamips-start.cmd“, “dg-local.cmd“, and “Network device list.cmd” script files, located in the DynMIPS installation folder:
(e.g.:
Before: start /belownormal /B /wait “Dynamips” “dynamips.exe” -H 7200
After : start /belownormal /B /wait /D “\Program files\Dynamips\” “Dynamips” “dynamips.exe” -H 7200
)
UPDATE: Check my next blog entry to download the updated startup scripts (.cmd) files.
Quick Start:
The Dynamips/Dynagen installation provides a number of samples to help you get started. The Windows installer places shortcuts to the samples folder on the Desktop and the Start-menu. You can also start any Dynagen lab file (these are files with .net extension) from the Windows shell or a command-prompt [e.g.: dynagen <lab-filename>]. But, before you do start a lab simulation, you must edit the sample lab file to specify the location of the Cisco IOS image that Dynamips should boot.
(e.g.:
- Navigate to Simple1 located in Dynamips samples folder (default: \Program Files\Dynamips\sample_labs\simple1)
- “Open with…” Notepad (or WordPad) Simple1.net
- Locate the following line:
image = \Program Files\Dynamips\images\c7200-jk9o3s-mz.124-7a.image
- Replace the path/filename with a valid Cisco IOS file location (e.g.: image = C:\labs\bin\c7200-is-mz.124-13b.bin)
NOTE: SmartNET customer can download IOS images from Cisco (http://www.cisco.com/public/sw-center/).
)
Booting:
- Start Dynamips server (Start -> Dynamips -> Dynamip server)
…or
Run: dynamips-start.cmd (located in Dynamips installation folder)
NOTE: Dynamips installation is setup to bind localhost:7200 (TCP); be sure to allow connections on this port. - Start the lab simulation by opening (double-click) the lab file (e.g.: Simple1.net) from Windows shell
By this point, you should see two console application windows (see image on the left). You can control the status of your emulated router by entering commands into the Dynagen application prompt (i.e., =>).
Dynagen basic commands: help, list, console, start, stop, suspend, resume, exit
Most commands require that you supply a router name (as shown by the list command), or the /all parameter to apply the desired command to all emulated routers (e.g.: start Router1 -or- start /all).
To access the console port of your emulate router, use the console command (syntax: console <routername> -or- console /all).

Ankit | July 17, 2007Hi,
I tried the steps u mentioned here for Vista. But i am getting error as below
Error: Could not connect to server: localhost
Also i am having AMD processor does it make difference for setup file. Please help me for this.
Hi Ankit: The messages usually means that dynamips server is
admin | July 17, 2007Hi Ankit: The messages usually means that dynamips server is not running. So, before you can execute/start a lab simulation, you must that dynamips server is running (which is a console (”DOS”) window; take a look at the images attached to this article).
Now, if the server is running, and you have UAC and Firewall enabled, they are most likely your suspects; as UAC will blocks proper execution of dynamips code, and the firewall blocks the default port used (TCP:7200).
I’m also assuming that you’ve used the dynagen installation package.
To resolve (assuming Vista with UAC enabled):
1: Give your user Full permission over the Dynamips installation directory (make sure to replace the permission for sub-directories as well).
2: You need to perform a little surgery on the batch files (.cmd) in the dynamips folder. I’ve posted the modified files here:
http://jsani.com/blog/wp-content/uploads/2007/06/dynamips-startup-scripts.zip
3: Run Dynmaips server as Administrator (either by modifying the shortcuts, or the right-click -> Run As Administrator process).
By the way, I doubt that your AMD CPU is at fault here (unless, your dynamips server is crashing, in which case, you’ll need to report the problem to its developer).
I hope this helps (if not, just ping me back with more info).

Hi Johan, Thanks for reply. I am the administrator and have
Ankit | July 18, 2007Hi Johan,
Thanks for reply. I am the administrator and have full permision for the folder. I started the server and its running fine. But when i run the network device list i am getting error for Wincap file. I doubt it might be due to AMD processor. Please let me know is there any different exe file for AMD processor. If i need to contact the developer whom i should send an email for this.
Ankit
Ankit: I hope you've been able to resolve the issue
admin | July 23, 2007Ankit: I hope you’ve been able to resolve the issue with the Network Device List utility (it’s been a few days since your messages); but, I’m certain the the problem is not due to your AMD processor. If you’re still experiencing issues, send me the exact message received.

Dipal | August 7, 2007Hi Mr. Johan,
I have the same problem with dynagen. The steps, youhave mentioned is been followed by me. But I get an error indicating ….could not connect to the server.
I am using windows xp system and dynamips is running as in administrator. I am new to ntworking field and new to all terms, so can you please help me solve this problem by giving explanations.
Thanks.

Hi Guys can please help me as i did all
David | August 23, 2007Hi Guys can please help me as i did all the installation but when comes to run i am getting an error message and when i press the enter key the of the network list close it self and the other one of dynagen.
the other thing that i don’t understand is do we just specify the the name of the image on the that notpad file or we have to download it and insert it in the the folder where we save the all lab thing .
thanks
david

Rishi | December 1, 2007Hi,
I am planning to buy a new Laptop (Dell 1520), 2GB RAM, Intel Core 2 Duo with Windows Vista Home Premium on it.
Is this configuration good for running DYNAGEN (6 38xx routers and 4 3500 switches)?
I came to know from my friends that Vista is not recomented for Dynagen. Is it True??
If I need to order the addtional RAM, Please advice.
